Fees for Unsterilized Dogs

Unsterilized dog fees are higher because thousands of dogs are euthanized annually or suffer as strays because of unwanted, unplanned litters that could have been prevented by spaying or neutering. One unspayed female and her offspring can produce 67,000 puppies in just six years. Also, sterilized dogs are healthier and have fewer medical problems. In addition, spaying and neutering can make pets less likely to run away or fight with other animals.
